Description:
The Model FL4000H is an advanced multi-spectrum infrared (MSIR) flame detector designed to provide superior false alarm immunity with the widest field of view. The FL4000H employs a multi-spectral optical IR sensing array with a sophisticated Neural Network Technology (NNT) system to reliably

Description:
Net Safety's Millennium Series Airborne Particle Monitor (APM) and Oil Mist Detector is an explosion-proof, infrared detector designed to monitor ambient air for particulate matter such as smoke, oil mist, carbon, dust or ash. This unique product is the ONLY detector of it's kind that is certified

Description:
Dual Sandwich Detectors or Two Color Detectors are mostly employed for remote temperature measurements. The temperature is measured by taking the ratio of radiation intensities of two adjacent wavelengths and comparing them with the standard black body radiation curves. THe advantages of optical

Description:
that either does not have such support or require additional support. AXIS P8221 complements Axis network video products and integrates easily into existing network video installations using VAPIX®.
Sensors such as a door switch, smokedetector, IRdetector or glass break detector—used

Description:
and other substances since both UV and 4.3 micron signals are attenuated, obscured or absorbed by thick smoke or detector lens contaminations. Also, these old technology UV/IRdetectors will not alarm to any fire if they are installed behind ordinary window glass.
The Fire Sentry FS20X detector uses

Emerson Process Management, RosemountEmerson Air Particle and Oil Mist Detector
The Millennium Smoke and Oil Mist Detector's advanced sensor technology utilizes a powerful, single-beam IR lamp with no mirrors to ever be contaminated. Sensor performance is not effected by high volume air velocity. Field adjustable zero level of obscuration as well as multiple sensitivity settings allows for fine tuning within specific application conditions to optimize performance and eliminate false alarms. The Millennium Series controller is an innovative line of explosion-proof...
